How To Root Samsung Galaxy S2 Android Device


Some couple of days back, I stumbled on a fellow blogger and a friend who uses a samsung galaxy S2 mobile device. Trust me, I asked him if he had rooted the phone and he said Yes. I actually played with the phone for a while and I must say the phone seems more complicated than my sony ericsson xperia x10i. Okay I know that sounds funny but the options on the phone or settings rather are just too much with lots of grammars been used.

Personally for me, if it wouldn’t take me more than 2 days or there about to fully understand the device and even play with other stuffs therein but what about a newbie? Well, am pretty sure most people won’t bother about that for as long as they can make and receive calls, send and receive messages and play music but for me, a mobile device should be more than that. I love exploring phones and that’s more reason I was able to install a custom mod to my sony ericsson android phone and the phone now works better.

Enough of long talks, let’s head over to the main subject matter of this post.

    Is rooting the equivalent of jail breaking in iPhones? I’m planning to buy a galaxy s3 next week. maybe I’ll have it rooted.

      Yes they are. In iPhones, its termed jailbreaking while on android, its termed rooting. We would appreciate it if you would send a report on how you rooted your s3 buddy.
